Jorge Lorenzo comes to the Japanese Grand Prix determined to close the gap on Casey Stoner in the overall standings as his title campaign reaches a critical stage.

The Spaniard, winner of the 2010 world championship, heads to the much-debated Motegi event 44 points behind his main rival, with just four rounds of the season now remaining.

It means he cannot afford to lose any more points to his Honda rival if he hopes to defend his crown, but as a former winner around the circuit, he is positive about his chances.

"Japan is a home race for Yamaha and for us it is always a pleasure to ride here. Motegi is a track where I have won before and last year I had a nice fight for the podium. I would like to win again here, so that is my aim this weekend.

"After all the confusion with Fukushima we are here, fit and ready to put on a good show for Yamaha in this special year for them. We will begin on Friday and try to do everything really well!"
